Hey teachers…if you follow a number of NASA accounts, just FYI some are being discontinued & consolidated into other accounts.
For instance, @NASAPersevere & @MarsCuriosity rovers will now be part of @NASAMars— dailySTEM Chris Woods (@dailystem)

Multiple NASA accounts on social media are being either discontinued or consolidated. If you followed any specific ones, you will need to change your settings.
Thanks to subscriber and friend, Chris, for sharing this.

Poisson was born exactly 244 years ago today. He introduced the Poisson distribution, used to model how often events occur in a fixed time or space.

The 2nd paragraph says:
One of its earliest practical applications came in 1898, when Ladislaus Bortkiewicz used it to analyze the number of Prussian soldiers accidentally killed by horse kicks.

RIP Betty!
Betty and her fellow code breakers were the unseen heroes who helped turned the tide in WWII.

A beautiful approach to find the area of a circle! You can convert a circle into a rectangle in a beautiful way.

A fun visualization to show another way to look at the formula for the area of a circle

All three symbols represent summation, hence the joke
About
This newsletter is my way of sharing interesting science-related news with my curious friends. I enjoy finding science and math connections in our world.
Please share this newsletter with others. Let’s encourage curiosity.
This is issue #78. 78 is:
a palindromic number in bases 5 (3035), 7 (1417), 12 (6612), 25 (3325), and 38 (2238).
the smallest number that can be expressed as the sum of four distinct nonzero squares in more than one way:
82 + 32 + 22 + 12
72 + 42 + 32 + 22
62 + 52 + 42 + 12
78 rpm was one of the early standards for record players set by the Gramophone Company in 1912
78 is the atomic number of Platinum, symbol Pt. Its name originates from Spanish platina, a diminutive of plata "silver".
From 1889 to 1960, the standard length of a “meter” was defined as the length of a platinum-iridium (90:10) alloy bar, known as the international prototype meter. The previous bar was made of platinum in 1799.
That’s it for this issue.
